I have a 2003 chevy duramax. Got it straight piped so the exhaust is loud...but I want the turbo to be louder. Is there a way to do this?

haha. Maybe a cheaper option. Will a k & n do anything?

Don't buy a k&n. They have oiled filters and the oil gets on the Maf sensor and causes it to go looney.

The stock lb7 turbo just doesn't whistle like the vvt on the lly+ models. I personally prefer the sound of the straight lb7 exhaust to that turbo whistle on the newer trucks.

oh and OVER oiling K&N causes issues. If you don't do that, it won't cause any problems

The BatMoWheel compressor wheel upgrades make the turbo a good bit louder if that is what you're after, they also spool quicker too!

Subscribed.... I'm in the process of taking my turbo horn off to see if my wheel has any play in it or marks on the fins, to see if I can find out what the hell that sound is coming from the turbo.. Those 3 bolts are a pain in the ass.. I started late and only got the top bolt out before it got dark and the skeeters came out, plus I need a longer 1/4" extension and a magnet so I don;t drop them damn bolts lol.... Thinking the bearing is shot, thats what it sounds like :(
